A human being is part of the world,
a part limited in time and space.
He experiences himself, his thoughts and feelings
as something separated from the rest:
a kind of optical delusion of his consciousness.
This delusion is a kind of prison for us,
restricting us to our personal desires and
the affection for a few persons nearest to us.
Our task must be to free ourselves from this prison
by widening our circle of compassion
to embrace all living creatures and
the whole of nature in its beauty.
Albert Einstein
